This is by far the best example of what NOT to do.... Once you get the idea, fast forward to about 2:35 for the hilarity to ensue.... Best punchline by the sound guy ever...
As much as tou all laugh now, I have seen this happen. I was rooting for the sound guy to cut sound and go "WOAH! You are fuckin up here! JUST hit your kick/snare!" So many guys I have seen (including myself at an early age) did this. No excuses. I was a tool!
